Will Hayworth updated CASSANDRA-11293:
--------------------------------------
Description:
Hi all!
I'm trying to using CQLSSTableWriter to load a bunch of historical data into my
cluster and I'm getting NullPointerExceptions consistently after having written
a few million rows (anywhere from 0.5 to 1.5 GB of data).
